Ithocritus ruber ( Hope, 1839 )

Lin, Mei-Ying & Yang, Xing-Ke, 2014, One new record species, Ithocritus ruber (Hope, 1839) from China (Coleoptera: Cerambycidae: Lamiinae: Petrognathini), Zoological Systematics 39 (2), pp. 309-312 : 309-311

Ithocritus ruber ( Hope, 1839) ( Figs 1–11 )

Monohammus ruber Hope, 1839: 43 (Assam of India); Hope, 1840: 441, pl. 30, fig. 5.

Ithocritus ruber ; Lacordaire, 1872: 449; Breuning, 1956: 354, fig. 1; Löbl & Smetana, 2010: 291; Lin & Jiroux, 2011: 108, figs 13–18;

N. Ohbayashi & Lin, 2012: 238, figs 1–5.

Supplementary description of female. Antennae about twice of body length, middle of 6th antennomere exceeding elytral apex. Antennomere ratio. Female: 34:4:89:74:61:56:53:47:45:42:66. Female genitalia ( Figs 9–11 ). The paraproct is very short and without baculi; the coxite lobes are very long and bear small styli; apex of coxite lobe and stylus ( Fig. 11 ) bearing tactile hairs; spermathecal capsule ( Fig. 10 ) with apical lobe more strongly sclerotized and apex expanded, but the very long and twisted stalk without distinct separations from both apical lobe and spermathecal duct; tergite and sternite VIII ( Fig. 9 ) with moderate long setae, more than half part of setae extending beyond apex; distinct lateral notch absent, basal pigmented patch present; tignum (= spiculum ventrale = anterior apodeme of sternite VIII, Fig. 9b ) much shorter than abdomen in ventral view, in our observation, tignum is 4.0 mm for a 13.5 mm abdomen.

Notes. N. Ohbayashi and Lin (2012) missed the distribution information of “Sikkim (coll. Itzinger); Silhet (coll. Lepesme)”, which was mentioned by Breuning (1956). Here we correct the mistake and add the new locality Yunnan of China.

Female of this species was described by Breuning (1936) and illustrated by Breuning (1936) and N. Ohbayashi and Lin (2012), but the female genitalia is described and illustrated for the first time. The easiest ways to identify female from male are: antenna shorter ( Figs 1–2 ); apex of ventrite V (sternite VII) with a bidentate protruding ( Figs 3–4 ); femora of fore legs without coarse wrinkling sculpture ( Figs 5–6 , male fore femora with coarse wrinkling sculpture in both inner side and outer side).

Male of this species was described and illustrated several times ( Hope, 1839, 1840; Lin & Jiroux, 2011; N. Ohbayashi & Lin, 2012), male genitalia was described and illustrated by Lin and Jiroux (2011). The specimen from Yunnan matches leg, inner side. 5. Male, showing the coarse wrinkling sculpture. 6. Female, without coarse wrinkling sculpture. Not to scale.
